A progress counter can affect both a message and an available action. Shared ownership of that information helps those parts of the screen stay consistent.
Local interaction and shared information have different scope
An expanded panel can be temporary state for one screen. The current signed-in account may affect much of the app. Both are state, but placing them at the same scope can make their relationships harder to understand.
A displayed value also needs a clear source. If a list and a detail screen show the same item's status, their agreement should come from connected information. State management concerns those relationships, rather than simply choosing a place to store every value.
